What is a PD charging port

    The biggest advantage of using a PD charging port is that it supports both front and back insertion. In addition, the PD fast charging protocol can also run higher charging power. USB-PowerDelivery (USBPD) is one of the mainstream fast charging protocols and a fast charging specification developed by the USB-IF organization. USBPD increases power transmission through USB cables and connectors, expanding the cable bus power supply capability in USB applications. This specification can achieve higher voltage and current, delivering up to 100 watts of power, and can freely change the direction of power transmission.

    The USB-PD protocol is a universal standard launched by the USB-IF Association in the United States to meet the needs of modern fast charging. This standard covers the previously owned protocols of Qualcomm, MTK, Huawei, and other companies while also standardizing them. Industry giants such as Google and Apple are accelerating their support for this standard, and this agreement has been recognized by China‘s Ministry of Industry and Information Technology‘s Taier Laboratory.
